"You are the only one who can meet that special need that he has in his life for intimacy," she wrote. "You're it. You're the only one. So don't forget that, that he needs you. So when you are exhausted at the end of the day, maybe from dealing with little ones, and you fall into bed so exhausted at night, don't forget about him because you and he are the only ones who can have that time together. No one else in the world can meet that need."

Michelle added, "And so be available, and not just available, but be joyfully available for him. Smile and be willing to say, 'Yes, sweetie I am here for you,' no matter what, even though you may be exhausted and big pregnant and you may not feel like he feels. 'I'm still here for you and I'm going to meet that need because I know it's a need for you.' "

As a mother of 19, the 49-year-old reality star has clearly put these words in action after they were given to her from a "dear friend."

"While I am always joyfully available for him, in turn, he'll lay down his life in any way," Michelle continued. "He will sit there and listen to everything I need to tell him because he knows that I'm there for him, too. I'm meeting his needs, he's meeting my needs. We're willing to be there for each other. And each one of us has different needs in a marriage relationship and that's what's so precious. I'll share this advice with Jill so she knows that she's got to be a wife first and then later, Lord willing, she'll be a mother."

For her second and third tips, Michelle digresses from the sex talk to acknowledge that privately working out disagreements and seeking out marriage counseling can also be important for maintaining a happy marriage.

"There are going to be those times in your marriage where you might not always agree; you might not see things eye to eye and sometimes you may need a trusted third party to be a counsel for you in your marriage," Michelle wrote. "Feel free to go to that trusted wise counsel that you both respect and get counsel when you need it. We have all been there."

But make no mistake, making whoopee is the crux of her marriage game plan.

"Jim Bob and I say we have the best love life ever because we're so experienced now, but we are also still learning about each other and it's just great," Michelle wrote.

This post comes after Michelle and Jim Bob 's niece, Amy (Duggar) King wed Dillon King last month.

Michelle and Jim Bob have been married for 31 years, but this past year may have been their most challenging. The family came under fire when their eldest child Josh Duggar, 27, found himself at the center of a molestation scandal. Josh admitted to molesting five underage girls, including his sisters Jill (Duggar) Dillard and Jessa (Duggar) Seewald.

He is currently seeking treatment at a rehab center after confessing to being unfaithful to his 27-year-old wife Anna.
